I've never refrigerated it. I store it in the liquor cabinet, and only bring it out on special occasions. They dont refrigerate it in Jamaica. It stays on a warm beach bar all day, every day. I know it says on the label that you should, but, I've never had a problem. If I kept it in the refrigerator, I'd have to drink it to make room for ketchup and such. It wouldnt last a week. I try to make 2 bottles last from trip to trip.
